DRAFT-EVENER.

Specification of Letters Patent.

Patented June 13,1916.

Application filed January 9, 19 15. 2 Serial No. 1,391.

To all whom it may concern:

Beit'known that I, CORNELIUS T. HAN- SEN, a citizen of the United States, residing at Big Sandy, in the county of Ohouteau and State of-Montana, have invented certain new and useful Improvements in Draft-Eveners, of which the following is a specification.

This invention relates to draft equalizers or eveners, and one ofthe principal objects of the invention is to provide an equalizer for attachment to a sulky or gang plow, and. adapted to be attachedto a. tractor having but one bull wheel running iii'the furrow, the equalizer being adapted for use with a four horse evener of the common type in such manner that one horse will be 7 placed in the furrow and three on theun plowed ground.

Another object of the invention is to pro: vide an improved equalizer of few parts and of extreme simplicity, and one which will be durable and eflicient in operation and inexpensive to manufacture. a

A further object is to provide an equalizer to be used in connection with a four, horse evener and arranged so that the equalizer may be shifted or set over relatively to the evener in accordance with the distance the plow is to be set over.

\Vith these and other objects in view which will become apparent as the description proceeds, the invention. resides in the construction, combination and arrangement of reference indicate like parts thrtuighoutv the several figures, of which F igure 1 represents a plan view of an equalizer constructed according to my 1nvention showing the same in use with a,

four horse evener. Fig. 2 represents a vertical longitudinal sectional view taken on the plane indicated by the line 2-2 of Fig. 1.. Fig. 3 represents a vertical sectional view taken on the plane indicated by the line 33 of Fig. 1. Fig. 4: represents a plan view of an equalizer constructed according to my invention showing the same in use with a tractor.

Referring more particularly to the drawing, a plow beam is indicated at 5 and at its forward end carries a cross clevis 6. A bar 7 is secured upon the cross clevis, and above the bar an arm or lever 8 is centrally pivoted asat 4:. This levercarries a clip 9 13. Theforwardend of the link is pivotedat 14 to one end of a draw bar 15. The opposite end of the draw bar is; provided with a plurality of openings 16, any one o-fwhich servesto receive a suitable pin 17, whereby a second link 18 may be pivoted at its; rear end. to the draw bar at the opposite end thereof from link 12. The forward end of link 18 is pivotally connected as at 19 to a four horse evener 20 of ordinary construction.

J ournaled upon draw bar 15 in alinement with plow beam 5 is a pulley 21. A chain or other suitable flexible element 22 runs over the pulley and is connected at its ends 'by'means of suitable clips 23 to the opposite ends of bar 7. The chain or flexible element 22 serves tomaintain the draft bar in parallel relation with the lever 8.

The draw bar 15 is made of two strips of material suitably welded or riveted together except along the portion where the pulley 21 and link 12 are connected, along which portion the strips are oppositely bulged away from each other so thatthe I pulley and linkfmay be connected to the draw bar between the strips and in the con tral line of the bar. K

It will be noted by the arrangement I provide that three of the horses will be placed to one side of the plow beam whereby they may tread upon the unplowed 7 ground, while the fourth horseis disposed in alinement with the ,plow beam and will walk in the furrow. Upon a pull in the direction of travel of the plow beam being imparted to the outer end of the draw bar.

through the medium'of link 18, the inner end of the bar will tend through the medium of link 12 to shift the arm or lever 8 backwardly at point 13 and forwardly at the endto whichthe brace 10 is connected,

thus imparting a forward pull to the brace and plow beam. The pulley 21 being in alinement with the plow beams co-acts. with the chain 22 in imparting the direct forward pull to the beam. The plurality of openings 16 is provided so that the four horse evener may be shifted relatively to. the draw 7 bar or 'viceversa in accordance with the distance the plow 18 to be set over OI'SlllftQd.

In Fig. at I have shown the manner in which the equalizer may be utilized with a tractor. The principle of operation of the device shown in Fig. l is substantially as that already described. In the figure, I have shown a portion of the framework of a tractor at 24:. The bull wheel is indicated at 25 and is adapted to travel in the furrow. The draw bar is indicated at 15 chain at 22*, pulley at'21, a lever at 8 the link connecting the lever and draw bar at 12, and the link'corresponding to link. 18 is shown at 18. nected by means of a link 26 with the cross clevis (3of the plow beam 5. The lever 8 is pivoted to the framework 24 at P in alinement with the bull wheel and the pulley 21*. The brace 10 is pivotally connected at its rear end at 9 to the opposite end of lever 8 fromthe end to which link 12 is connected. Said brace 1O at its forward end is provided with a chain 27. The chain is connected at its free end to the framework 24 at point 11 in alinement with the bull wheel and points 4* and 21 The pulley 9.8 is provided on the framework over which the chain 27 extends. The brace 10 and chain 27. are substituted for and perform the function of brace 10. The ends of chain 22 are connected at 28 to the framework 2% at equidistant points from pivot point 4i. The main differences in the arrangement shown in Fig. 1- from that shown in Fig. 1,

is that the direction of pull through the various parts is reversed, the principle upon which both devices operate being the same.

Although I have described the preferred embodiment of my invention, I may desire to make such changes in the construction, combination and arrangement of parts thereof as do not depart from the spirit of the invention and the scope of the appended claims.

I claim 1. The combination with a plow beam, of

a bar secured transversely thereof, a lever centrally pivoted upon the bar at a point in alinement with the plow beam, a brace connected at one end to the plow beamv and at its opposite end to one end of the lever, a link pivotally connected at its rear end to the opposite end of the lever, a draft bar pivotally connected at one end to the link at the forward end of the latter and extending transversely of the plow beam, a pulley journaled upon the draft bar in alinement with the plow beam, a chain connected at its ends to said bar on opposite sides of the plow beam, and engaging over said pulley, a second link pivotally connected'to the end of the draft bar opposite the end to which first said link is connected, and a four horse evener pivotally connected to the second This link is pivotally con-- link, in such manner that when draft animals are hitched thereto one of them will be in alinement with the plow beam, and the others will be disposed on one side of the plow beam, substantially as described.
